Effects of the Electrodes’ Shape and Graphite Quality on the Arc Stability During Hydrogen Plasma Smelting Reduction of Iron Ores

open access: yesSteel Research International, 2023
Reducing greenhouse gases (GHG), especially CO2, is necessary to counteract climate change. The European steel industry currently corresponds to 5.7% of the total EU emissions and must therefore minimize their GHG fractions in the future. One of the most

Study on hydrogen smelting reduction behaviour in synthetic molten HIsarna slag

open access: yesIronmaking & Steelmaking, 2023
The reduction behaviour of hydrogen with FeO in synthetic molten HIsarna slag has been investigated using two experimental methods: (1) Blowing 5% or 10% H2-Ar onto the molten slag at 1450°C, 1475°C, 1550°C, respectively; and (2) Injecting 10% H2-Ar into

Recovery of Cu-Fe Alloy from Copper Smelting Slag

open access: yesMetals, 2023
Copper smelting slag usually contains 1–6 wt% copper, which can be recovered by pyrometallurgical and flotation processes. However, the tailing slags still consist of 0.3–0.7 wt% Cu and 35–45 wt% Fe equivalents to those in the copper and iron ores ...

Smelting separation behaviors and mechanisms of high-alumina rich-manganese ore obtained from metallic reduction and magnetic separation [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2019
In this paper the smelting separation of high-alumina rich-manganese ore prepared with selective reduction and magnetic separation was proposed to produce the high carbon ferromanganese alloy (HCFeMn). The rational smelting separation parameters for high-
